Look at the Geobar with the class and ask them to guess what ingredients are in it and then to estimate how much of each ingredient there might be. Which ingredients do they think are Fairtrade? Why?

Main Activity
Explain that they are going to use the ingredient list on the back of the bar to explore the different ingredients which make a Apricot Geobar and then work out their proportions, as well as think about how many of them are Fairtrade. Working in pairs or groups pupils complete the worksheet tasks.

Geobars and Fairtrade certification
Geobars are composite products. This means that they have many ingredients. These ingredients are a mixture of Fairtrade ingredients and non-Fairtrade ingredients. Fairtrade ingredients are represented on the ingredients list in bold, with a star (*) next to them. To be Fairtrade certified producers have to meet certain requirements laid out by the Fairtrade Labelling Organisation (FLO) and the Fairtrade Foundation. Eksteenskuil Agricultural Co-operative (EAC) received their Fairtrade certificate in 2003 to export Fairtrade raisins. In fact, until 2009 they were the only Fairtrade raisin producer in the whole world!

Geobars are still Fairtrade Marked even though not all ingredients are certified because they match the requirements laid out by the FLO.

Depending on the flavour of the Geobar the total percentage of Fairtrade ingredients is between 47.8% and 59.1% of the Geobar. This may not sound like a lot, but for this kind of product it is a very high proportion. Traidcraft are working all the time to ensure that all the ingredients which can be sourced from Fairtrade providers, are. 

Split children into groups and provide each with a set of percentages. Each child takes a number. They then put themselves into order of largest to smallest.

Pupils use their list of ingredients to estimate and weigh out different amounts of the ingredients (remembering to use Fairtrade!) and then make their Honey Nut Geobar. Alternatively, pupils follow the same process for the other Geobar flavours and then compare their results. Were their proportions and estimated amounts of ingredients correct?
